CVE-2025-23084: A vulnerability has been identified in Node.js, specifically affecting the handling of drive names in the Windows environment. Certain Node.js functions do not treat drive names as special on Windows. As a result, although Node.js assumes a relative path, it actually refers to the root directory.
On Windows, a path that does not start with the file separator is treated as relative to the current directory.
This vulnerability affects Windows users of `path.join` API.

FAQ
Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
